title: [Eczematous dermatitis: contact or/and atopy...].
abstract: The diagnosis of eczema and its etiology is mainly based on patient's history and meticulous clinical examination. The careful anamnesis should include all personal and familial signs of atopy and all patient's contacts mainly localised on the eczematous skin. Many investigations may help us to better understanding of this complex problem: blood examination (total IgE, Rast), prick-tests, epicutaneous or patch-tests (PT), semi-open tests (SOT) for potentially irritant products and repeated open application tests (ROAT) made by the patient himself. This tests will never be made systematically but always depends on the patient's history and the clinical examination.
